A modern programming language that makes developers happier.

kotlinlang

Totally not a js dev. 
I'm using a js lib (puppeteer) that needs `const browser = await puppeteer.launch()`. 
My issue is that I can't use await with kotlin js, and I don't know if "await" is just syntactic sugar for a callback (sort of stuff done on Java with coroutines)

Check out this gist, and the related forum thread <https://gist.github.com/nosix/5994e53d5bef20292b998d6690649dc1> <https://discuss.kotlinlang.org/t/async-await-on-the-client-javascript/2412/3>

In JS, `async/await` is pretty much just syntactic sugar over the Promises API <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function>. So if `puppeteer.launch()` needs to be awaited, it really just returns a `Promise` object, and you can then wrap that up in a Kotlin coroutine

Thanks, that's exactly what I was looking for

You can use kotlinx.coroutines to have `await()` extension for promises
